How do I replace front oxygen sensors? (O2)
Hey everyone - I searched but couldn't find a schematic or garage post about how to replace the two front oxygen sensors. I'm throwing code P2251, so just ordered the new sensors and would love to put them in this weekend - car is at 90k miles, so I figured I would just replace both of them. Any diagrams to share? Thanks!

Removing the tower strut bar will make it easier (3 nuts each end, 21 ft-lbs), 2 bolts on right side, 1 bolt on left side http://i263.photobucket.com/albums/i...sorremoval.jpg |
Thanks - when I wrote "front" I was trying to separate from secondary sensors after the cat. Quick follow-up - what's the best way to reach Bank 1 - from the driver side? I just bought the car 2 months ago, so am learning exactly where everything is located. :)

There are actaully 4. 2 upstream (pre-converter) and 2 downstream.
http://www.acuraautomotiveparts.org/...s=&view=normal These should be them. 36531-RCA-A02 SENSOR, LAF 36531-RDM-A01 SENSOR, FR. LAF 36532-RKB-004 SENSOR, FR. SECONDARY OXYGEN 36542-RKB-004 SENSOR, RR. SECONDARY OXYGEN |
Why just replace the one??? I'm at 134,000 miles and just trying to keep up on things, should I be replacing all of them with my mileage???

Keep in mind the computer is always checking the sensors, so if there was a big problem, you would get a Check Engine Light. For those that want a writeup on changing the sensor, I put one together last week but put it in the "Problems & Fixes" subforum: https://acurazine.com/forums/3g-tl-problems-fixes-114/e-130-diy-oxygen-o2-sensor-installation-rear-upstream-f-aka-p2251-811823/ |
Oxygen sensor (Bank 2, Sensor 1) for Acura RL 2005
Acura RL 2005 got Code P0154 and P2254, Where can I got the Oxygen sensor for Bank 2, Sensor 1.
Many thanks! Neil |

Hey, I don't recall having any symptoms before the code was thrown, but it was 6 years ago...:tomato: Has the throttle body ever been cleaned?
